| Summary: | A method used to improve the hardness of aluminium alloy is by applying age hardening process. The process in age hardening were solution heat treatmen, quenching, and artificial aging. At phase of artificial aging can be conducted by some variation. The variation able to influence the result from process of age hardening. The aim of the research was to analyze the effect of temperature and holding time artificial aging to hardness of alumunium alloy. The alumunium alloy used for the research was ASSAB Prodax. The method used in the research was experiment method. The independen variables were temperature artificial aging and holding time artificial aging. The dependent variable was hardness of alumunium alloy. Variation temperature of artificial aging at 1200C, 1500C, and 1800C. Variation holding time of artificial aging at 2 , 4, and 6 hours. Based of the statistic analysis with anava two way to the data gathered from the research, it can be stated that the temperature artificial aging at 1200C and holding time artificial aging at 6 hours resulted in improving hardness (78,98 HRB). |
